I'm new to CPA gateway and I wanted to test out BHCB on one of my idle domains. When I installed on one of my domain under main directory on my WP blog(idle domain), it worked perfectly. Then I installed it on another domain under a sub-directory(active blog), it just does not work(no bhcb on the main directory, only on sub-directory). I think I configured everything, but it just refuses to function. Can someone give me a helping hand please? Thanks.
